Is there a quicker way without using loops? Not really (and a loop will a matter of seconds at most), but there are neater ways such as DF[] <- lapply(DF as.factor) which will convert it for you. Or you could get read.fwf() to do so: see the colClasses argument to read.table, as mentioned on its help page. -- Brian D.
